SPRING-WHEEL.`

- Specification of Letters Patent.

' Patented March 5, 1907.

Application filed vltpri121, 1906. Serial No. 313.064.

To'all whom t may concern,.-

Be it known that I,

in the county of Saline and have invented certain new and useful Improvements in Spring-Wheels, ofi which the ollowing is a specification.

This invention has relation to vehiclewheelsprovided with yieldable tires, so as to neutralize shock and vibration, and thereby add greatly to the comfort of the party riding in a vehicle mounted upon wheels of the character mentioned.

The inventionappertains more particu* larly to the vclass ofwheels embodying a lmev talllc tire and sprlngs interposed between and aims to y rela'ced by .accom partin the felly and rim ofthe wheel, provide an improved structure means whereby any one of the rings may be easily and quickly er for purposes vof repair or to be a new spring.

`knowledge of the details of construction of v EDWARD B. SIMS, a citi-l zen of the United States,'residing at Western, State of Nebraska,

the means for effecting the result reference is to be had to the following description and aning drawings.

Wh1 e t e invention may be adapted to diiferent forms and conditions by changes in the-structure and minor details without defrom the spirit or essential features thereo still the preferred embodiment is own in th Figure 1 is a side view of avehicle-wheel embodying the invention. Fig. 2 is a detail perspective View of a portion of the rim, showing the parts on a larger scale. Fig. 3 is a transverse section of the outer or rim or- 1 4 is a transverse section of thetire, showingg Vthe covering upon the outer side and the securing means therefor.- F' 5 is -a detail view of the' inner end of a spring, showing the keyhole-slots formed therein. Fi 6 is a def tail '.view lshowing'the manner o1g placing a spring in position.

Corresponding and like parts are referred to inthe followin description and indicated in all the views olig the drawings by the same reference characters A T The wheel may be of any design ormake, style of `vehicle for which it 1s designed. The felly v1 ofthe wheel may be of metal or wood or acombination thereof or e accompanying drawings, in"

of any suitable material. The tire 2 is 'continuous and is preferablycomposed of spring metal, such as steel, and is provided at intervals in its circumferential length with pairs of ears 3, to which the outer ends of springs 4 are pivotally connected bymeans of pins, bolts, or

like fastenings 5, passed` through registering openings in the ears 3 and at the outer ends o the springs 4. The ears 3 preferably form parts of strips which are bent near their ends angle to the body of the about ata right being riveted or otherwise strips, .the latter fastened to the inner side of the tire 2. The openings or eyes at the outer end-s of the springs 4'may be provided in any manner, preferably by bendingend portions of springs upon themselves into cylindrical form. l

The springs 4 are preferably curved, being of semicircular form, which has been found togive is distributed uniformly throughout the springs, thereby enabling the saine to be constructed of comparatively light material. '.l' 1e inner ends of the springs are connected to thefelly or rim 1 ofthe wheel in any manner. 1t is proposed to detachably connect the inner ends of the springs with the felly or rim, thereby making provision for re-l moving any one of the springs either to substitute the same by a new one or for any desired purpose. 'l'o attachment and detachment of the springs, keyhole-slots 7 and 8 are provided at the inner ends thereof, the slots 7 being at a right angle to the slots '8. Headed studs or fas- ".teners 9 are attached in any substantial manner to therim of the wheel, the heads of said fasteners being of a size to pass readily through the enlarged portions of the slots 7 and 8 and the neck of said fasteners corresponding to the contracted portion of the slots. The space between the heads of the fasteners and the rim corresponds exactly thickness of the springs, obviating any play of the latter. A pair of studs is had for each spring, one stud or fastener entering the slot 7 and the companion When placing the springs in position, the head of one stud of a pair is passed through the enlarged part of the slot 8 ofthe s ring, and the latter is moved longitudinal in the contracted part of the slot 8, after which the spring is turned laterally to cause the other' stud or fastener of the pair to pass the provide for the ready i' y to bring the fastenerl the best .results,"since the end thrust roo IIO

.for any urpose, the same may be readily effected y'disconnecting its outerv end from the ears 3 ,to which it is connected, and subsequ'ently turning the spring to bring the head of thefastener in alinement with the enlarged portion' of the slot 7 thereof,`and

-after said slot'7 has been disconnected from 'the cooperating fastener the spring is moved tO'bring the companion stud in register with the enlarged portion of the slot 8, thereby freeing the spring, as. will be readily cornz5v v obviate noise, its outer side is coveredwithv.

As additional securing means metal strips 11 are passed-transversely through the covering 10, and the projecting ends are bent about opposite edges oil the tire, as indicated at 12. The transverse strips 11 provide' ribs which are -of special advantage to increase traction into. the
